LEGO Technic Worm Drive and Linkage Mechanism
Вставка
- Опубліковано 2 жов 2024
- This mechanism takes advantage of the fact that the LEGO Technic Worm Gear is free to slide along an axle. As the black vertical axle rotates, the worm gear rotates an 8 tooth gear, which rotates a linkage, causing the mechanism to move up and down.
This mechanism allows rotational motion to be converted to reciprocating linear motion, which can then be used in larger, more complex mechanisms to achieve any number of useful movements.
See an implementation of this mechanism here: • Caterpillar : LEGO Tec...
This mechanism was inspired by the following video:
• Worm drive and linkage...
If you are interested in in these sorts of mechanisms, and you haven't seen Nguyen Duc Thang's channel yet, I highly recommend that you check it out: / thang010146
You can see a nice implementation of this mechanism in the following video:

Wow this is a interestingly simple and easy way to transform rotational movement into directional movement. Interesting
thats an anti-engine then
I took me a moment to realize how it worked, but it amazing
I never seen this type of linear actuator. Pretty smart, and it looks sturdy as well.
Can I find all of the parts in Lego Education 9686 ?
No. Set 9686 doesn't have the these exact same parts.
However, set 9686 has a lot of great parts and it does have the key parts to make this model: motor and battery box, worm gear, other Technic gears and liftarms. You might not be able to make this model exactly like in the video, but you can make the mechanism with substituted parts.
This could be part of a wheel mechanism or piston mech
Use it in a GBC to lift a ball out of one cup and move it to another around a circle.
@@MrDgwphotos oh yeah
Great idea and well executed! But it sounds creepy
it took me 50 secs to realise what happened
You basically made a piston. That's pretty awesome
How. Mesmerising. I. Cannot. Look. Away.
I can so see someone turning this into a turret roatation/ firing cannon system for a Lego tank.
Jesus this is just brilliant!
very cool
Cool. And what can you do with this function?
+Jason Hunter - I have used this within my Braiding Machine (ua-cam.com/video/CE2j7Fi49lg/v-deo.html), but it can be used anytime you need to convert a rotational movement in to a reciprocal movement.
+slfroden That's so cool. If you have any other examples it would be great to see. I'm curious.
+Jason Hunter - Thanks. I've only used this mechanism just the once so far.
Cool. I need to get some Legos and think of some other uses.
so, did you ? xd lets see
Nice
I was looking through old videos I liked. I'm pretty sure I saved this one because I didn't understand it the first time. How do you control that first motor so perfectly? it takes a while for them to stop and start moving in the other direction, and this type of lego is mostly analogue. I can see the remote for the motor on the upper left corner. What is controlling the remote?
Anyway, it's not one smooth single direction movement. If it would be, the worm gear would just go out of the axle at the top, or bottom. And you can actually hear the motor having to stop and restart all that gearing inside.
At the upper left is the IR receiver, which is controlled by an IR controller/transmitter. I can't remember which one I used, but I think I used the Train IR Controller which lets you control the speed of the motors.
The motor in the middle is on all of the time, but as the worm gear goes up it has to struggle against gravity a little bit. The worm gear then turns another gear which is linked to the base which makes it go up half of the time, and down half of the time. The linkage stops the worm gear from sliding off the end of the axle. It looks like it pauses at each end, but that is just because of the rotary-to-linear motion (sin wave).
I only turn the motor at the lower left on after a few seconds, and that is so the whole mechanism can rotate so you can get a good look at the mechanism for all sides.
Just one question: WHY
+Gamel LP - Why not?
This mechanism allows rotational motion to be converted to reciprocating linear motion, which can then be used in larger, more complex mechanisms to achieve any number of useful movements.

that still begs the question whyyyyyy
but nice build!
👌 noice!
At first I was like.........
why at first
why at second?
it can be with the help of your imagination
Wow amazing
Hey, can you tell me what parts I need to buy to make this please?
I don't have a complete parts list for this model, and I no longer have this model assembled.
The main part that you will need is a Technic Worm Gear (part 4716).
Keep in mind that this is just a prototype model, so all other parts can be replaced with whatever you find works best.
If you change the size of the gear and/or the linkages, you will get different results.
If you already have some Technic pieces, I recommend playing around with different configurations to see how it operates.
But what's the point of it
This mechanism allows rotational motion to be converted to reciprocating linear motion, which can then be used in larger, more complex mechanisms to achieve any number of useful movements.

GREAT JOB ONCD AGAIN!!!

cool
that looks like quite overengineering
I'm sorry, I don't understand.
How is this overengineered?
so simple and AWESOME!
where can I find these parts ?

I have don the same but I screw my little gear
What I did wrong?
+Kodizar - I'm not sure what you did wrong. Did you construct it the same as I have done? Are there any differences?
at the weakend Im gonna build it again carefully and I will let you know
a year later...
os funny
brilliant
I AM GONNA BUILD THIS MAN
How to create
I don't have any detailed building instructions or tutorial for this mechanism, but if you have the required LEGO pieces and study the video closely you should be able to recreate it easily enough.
Mấy cái máy đó là anh tự chê à
Google Translate: "These machines are self-destructive"
If that is the correct translation, I'm not sure what you mean. This mechanism can happily run without destroying itself.
such cool
very wow
Hát ez marha nagy , roppant kreatív !
Which Lego set use?
I didn't use a specific single LEGO set to make this. I used a variety of LEGO Technic pieces that I had. The main pieces that you will need to recreate this mechanism are the worm gear and the motor.
